What to specify
Confirm the exact engine model, alternator, controller, standby/prime rating, cooling package, fuel tank, breaker, canopy and warranty.
Silent or open
Open sets suit engineered rooms; silent canopies simplify outdoor or noise-sensitive sites but still require airflow, exhaust and service clearance.
Integration
ATS, cabling, earthing, protection and commissioning determine how the set behaves when grid power fails.
Buyer checklist
Verify the complete project scope
Confirm exact equipment model and rating, scope of supply, installation responsibility, commissioning, warranty, spare-parts path and after-sales support. For industrial power projects, the lowest initial price is not automatically the lowest lifecycle risk.
Advanced buyer notes
For meaningful comparison, normalize the exact technical specification, installation and commissioning scope, written warranty, spare-parts route and after-sales response. Search rankings, company names and import volume are useful discovery signals, but the project decision should be based on equivalent technical offers.
Research methodology and freshness
PS Group research pages separates company claims, public third-party data and general engineering guidance. Dataset-specific figures are labelled with their scope; competitor names are used for buyer comparison without implying affiliation; and technical values are treated as references until verified against the final project and manufacturer documentation. Last reviewed 21 September 2026.
Evidence worth requesting before purchase
Ask for the manufacturer data sheet, serial/model references, warranty terms, commissioning checklist and a clear list of inclusions and exclusions. For high-capacity or critical installations, request evidence of load testing and confirm the site engineering assumptions before delivery.
Brands commonly researched in Bangladesh
Industrial buyers frequently research Perkins, Cummins, Ricardo, Mitsubishi, Volvo Penta, Yanmar, Weichai, Yuchai, MTU, Baudouin, Doosan, Lovol. The practical comparison is not only brand versus brand: exact engine model, complete genset configuration, project duty and after-sales support determine whether a proposal fits the application.

Frequently asked questions
What kVA Perkins generator should I buy?
Size from actual load and starting current rather than choosing a round catalogue number.
Are all Perkins sets the same?
No. Assemblers combine Perkins engines with different alternators, controllers, canopies and accessories.
Do I need an ATS?
Most automatic standby installations use an ATS or equivalent transfer arrangement.
